Battery breaker
This circuit breaker provides over-current protection and is used as an on/off switch for the battery power. It
must be switched on for proper Alpha FXM operation.
Battery connector
The battery connector connects the external batteries to the Alpha FXM.
RJ45 communication module connector
This RJ-45 connector is the Alpha FXM Ethernet connector.
LCD control panel and menu navigation buttons
The LCD control panel together with the cancel, scroll and select buttons are used to monitor and control the
Alpha FXM350.
USB communication connector
This USB communication connector provides a direct connection to the USB port of a standard computer USB
port (USB 2) for remote monitoring.
Battery temperature sensor connector
The battery charging voltage is temperature dependant. A battery temperature sensor connects to the Alpha
FXM so that the Alpha FXM microprocessor can adjust the charging voltage for optimum charging.
The sensor MUST be attached to the Alpha FXM for normal operation. If the sensor is not attached, a
“Temperature Probe Unplugged” alarm appears on the LCD.
Battery voltage test points
These test points let you measure the battery voltage. They accept 2 mm diameter test probe tips. The battery
circuit breaker must be on to measure the voltage.
The battery voltage test points are not to be used as a power outlet.
Optically isolated user inputs
These optically isolated inputs are used to attach an external switch panel for remote control of the Alpha
FXM.
The User Input connector has three contacts (Figure 4) that are used to control the Alpha FXM. The default
settings for the user inputs are as follows:
1.
(S1): Shorting this contact to Common starts the Alpha FXM battery test. See "Battery Test" on page
95.
2.
(S2): Shorting this contact to Common activates an alarm. See "7.3.4.9 Maintenance > User Input" on
page 63.
3.
(SC): Isolated return for contacts S1, and S2.
Additional user inputs and dry contacts connector
Enables connection to 3 dry contacts and 2 user inputs on the Micro350 top panel or to optional rack mounting
ears (see Figure 20).
